Bug#501: Missing function: Authentication Forwarding
by Hadmut Danisch 13 Nov '14

13 Nov '14

Package: x2goclient Version: 4.0.1.1-1ubuntu1 Hi, the current x2goclient lacks a highly important feature, the Authentication Forwarding of ssh. Would be nice to have it. The pyhoca-client does support this, but unfortunately does not come with a Mac OS X dmg package for easy installation. Since this is essential for remote working, it would be really important to have this feature in the plain x2goclient. Best regards Hadmut

Bug#501: X2Go Client and SSH agent forwarding
by Mike Gabriel 13 Nov '14

13 Nov '14

Control: severity -1 important Hi Hadmut, thanks for reporting your feature request: SSH agent forwarding for X2Go Client. Please note, that pyhoca-gui (the alternative X2Go client application) already supports that. We also just fixed an issue on X2Go Server: now SSH agent forwarding stays intact for resumed X2Go sessions. I raise the severity of your bug report to important, we should really get a solution for this into X2Go Client soon.

Bug#672: SSH-Agent-Forwarding in pyhoca-gui does not survive reconnects
by Robert Siemer 12 Nov '14

12 Nov '14

Package: x2goserver Version: 4.0.1.18 Pyhoca-gui supports SSH-agent-forwarding, but that doesn’t survive a reconnect with session resumption. As far as I understand the following happens: (-pyhoca is configured to do SSH-agent-forwarding) -pyhoca connects via SSH to the X2Go server -the sshd creates a unix domain socket in /tmp/ssh-XXXXXX/agend.PID -the sshd sets SSH_AUTH_SOCKET containing the name of the socket -sshd starts whatever is requests by the X2Go client having that environment -SSH-agent-forwarding works whenever the SSH-connection dies (proper session suspend with disconnect or connection is “cut”) it continues like this: -SSH is connected again -unix domain socket and environment is set up, but -the programs (the X11 clients in a resumed X2Go session) are still running in the old environment with outdated SSH_AUTH_SOCKET info -the programs from before can’t access the SSH-agent -...unless the new value gets setup in the old environments possible fix is this: -X2Go on the server side does not start any new programs in the X2Go session or resumes an X2Go session, until: -an only-session-dependent symbolic link is set up pointing to the socket from SSH_AUTH_SOCKET -SSH_AUTH_SOCKET is set to that symbolic link Result: -as the name of symbolic link is fixed for the session, no environment variables need to be updated -the link always points to the socket created by the sshd for this connection -the ssh-agent can be reached

X2Go QA brain storming session
by Mike Gabriel 12 Nov '14

12 Nov '14

Hi All, Kjetil from fleten.net and I just had an X2Go QA brain storming session. The context is a school project with a 2 months duration about the general topic QA. The teachers at that school addressed Kjetil in the search for possible QA projects. We arranged for an X2Go QA project with that school, starting in two weeks' time (or so) from now. Being aware of several approaches one could take for software QA, we chose a very simple and feasible approach (considering the short period of preparation time). X2Go currently offers two clients (X2Go Client, PyHoca-GUI). These two clients run on various Linux distributions, MS Windows and Mac OS X (X2Go Client only). These two clients connect to Linux servers running X2Go. The possible scenarios on X2Go Servers are so versatile, that we definitely need to exclude many possible scenarios from testing and only focus on some. As this project is supported by Kjetil's company as a non-profit project, we will as a first step focus on testing current X2Go features that are provided to customer's at fleten.net. So the gain for fleten.net is intensive testing of a setup similar to what they provide to their customers. The gain for the X2Go project is a matrix / a scheme for testing current X2Go features in various contexts. The idea is that others jump in and enhance the methodology, increase the number of tests and automize parts of the tests, as well. The final goal is that someone comes in who really knows how software QA works and set up a proper QA scheme for X2Go. Not now, but as a final goal. For X2Go QA, Kjetil and I were of the same opinion, that never any X2Go component should ever "call home" if an error occurs. This is about respecting people's privacy when using X2Go software in the first place. Also, a potential "calling-home" feature should definitely be optional (the user gets asked, if a bug report is to be sent...). However, from experiences with MS Windows and also with recent Ubuntu versions, this extra bit of requiring a certain user interaction is not something we want the user to burden with. What we will work on during this week: Provide a(n incomplete) list of X2Go features and compile information about which of the two clients supports what feature. Months back, I already started such a list (but got distracted by other stuff). Kjetil will fill in more features and rework that list, whereas I will review and edit that list later-on. We work on this list via the X2Go wiki [1]. Potential subprojects for the student project could then be: (1) o Create a general remote desktop computing feature list (what would I expect from a remote desktop computing software) o Create a list of X2Go features o see how these two list match... (2) o Create a matrix for X2Go feature testing o Not all features can be tested, as this maybe goes beyond the scope of this student project (3) o Some students could work on jenkins based package installation tests (after new nightly build packages are available) (4) o Students can focus on X2Go Server / X2Go Client / PyHoca-GUI debug messages and see if there are log messages that are: - useless (and should be silenced) - really helpful for debugging - are useful for heavy debugging, but obfuscate log message output -> change log levels of certain debug messages o Basically, the debug output of X2Go Server / Client / Python X2Go should provide\ easy-to-read information on what the actual problem of the user is. (5) o Translate better between server-side errors and reporting them on the client-side (big task!!!) (6) o The QA testers need to be able to use the X2Go bug tracker, so that they can provide information to the X2Go BTS if tests fail. (7) o ... (??? any input from others ???) So far to the summary of what we are currently working on. If people have input on this and that or ideas, please feel free to enhance our discussion. For next week, we will schedule a meeting with the QA teacher of the school that we are about to cooperate with. Part of the project will be that I (Mike#1) will come to Denmark and visit that class of students and provide support at critical points of the project (integration). light+love, Mike [1] http://wiki.x2go.org/doku.php/wiki:development:x2go-qa -- DAS-NETZWERKTEAM mike gabriel, herweg 7, 24357 fleckeby fon: +49 (1520) 1976 148 GnuPG Key ID 0x25771B31 mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

Bug#670: window border and control disappears after maximize and move
by Anand G. 11 Nov '14

11 Nov '14

Package: x2goclient Version: 4.0.3.0 x2goclient-4.0.3.0-20141021 Windows 7 64-bit SP1 Laptop connected to a USB docking station supporting two monitors. Laptop is display #1. Monitors attached to dock are displays #2 & #3. Order of displays is: 2, 3, 1 from left to right. This is according the the "Identify all displays" button in session preferences. Laptop is running at 1600x900 Monitors #2 & #3 run at 1680x1050 x2goclient session type "Single application" command is xterm. session settings: Custom display (800x600), dpi is 96, Xinerama extension unchecked Start new session and xterm opens on display #2 (left most screen). xterm maximizes correctly. Upon dragging maximized xterm from display #2 to display #3 (middle), the window manager/border disappears. I can no longer manipulate the window (minimize, maximize, restore, move) and it occupies the full screen. I have to suspend the session, undock, and then resume the session in order to regain control of the window. Simple suspend/resume does not work. Applications launched from the xterm behave the same way (e.g. lose window control over gvim session). The problem is not there with client 4.0.2.1+hotfix1+build6. Everything works as expected. The maximized window correctly snaps between displays. I do not have x2goserver settings or version information available.

Kongress Neu-Ulm
by Jos 11 Nov '14

11 Nov '14

Booth & Talk @ IT-Kongress, University of Applied Sciences, Neu-Ulm, Germany (2014-11-13) :!: Note that the talk will be in German. Title: X2Go - an OSS Remote Desktop and how it is used in companies Various users and contributors to the project will talk about and/or demo their individual use cases. Hi all, Is it possible to get these demos on video? I think it is really important that an overview of this can be put on the wiki site. Potential users need to see implementations in action!, so we need to get more video material on air. Regards, Jos.
